Weed control and shrub trimming

Whether you are reclaiming an overgrown jungle or looking for a seasonal tidy-up, hiring a professional gardener ensures the work is done safely and at the right time of year for each plant species. This guide breaks down the costs, timelines, and considerations for homeowners in 2025/26.

What Does the Work Involve?

• Site Assessment: Identifying weed species (including invasive plants like Japanese Knotweed) and assessing the health and pruning needs of various shrubs.
• Weed Eradication: Removing weeds by the root or applying professional-grade herbicides, depending on the surface and surrounding plants.
• Shrub Pruning and Shaping: Trimming overgrown branches, removing dead or diseased wood, and thinning out dense growth to improve plant health.
• Border Maintenance: Edging lawn borders and clearing debris from flower beds to create a clean, defined look.
• Waste Management: Collecting all green waste (arisings) for on-site composting or off-site disposal.
• Preventative Care: Applying mulch, bark, or weed suppressant membranes to treated areas to inhibit future weed growth.

Typical Costs

Prices for gardening services vary based on your location in the UK, with London and the South East typically seeing higher rates. Most gardeners charge by the hour, though some may offer a fixed price for a specific "clearance" project.

The total cost is primarily influenced by the level of neglect. A garden that hasn't been touched in a year will require significantly more labour and generate more waste than a garden under a monthly maintenance contract.

How Long Does It Take?

• Small Front Garden Tidy: 1–3 hours for basic weeding and light trimming of 2-3 shrubs.
• Average Semi-Detached Back Garden: 4–6 hours for comprehensive border weeding and shaping several large shrubs.
• Large or Overgrown Garden: 1–3 days, often requiring a two-person team to clear heavy brambles and reduce large hedges.
• Monthly Maintenance Visit: 2 hours for a "keep-on-top" service during the growing season.

DIY or Professional?

Light weeding and basic hedge clipping are manageable DIY tasks for many homeowners. However, professional gardeners bring specialised equipment like long-reach trimmers and industrial shredders that make the job much faster.

Crucially, professionals understand the pruning calendar. Pruning a spring-flowering shrub at the wrong time of year can mean no flowers for the following season. Furthermore, the use of professional-grade weedkillers requires specific NPTC qualifications (PA1/PA6) to ensure they are used safely around pets, children, and watercourses.

Note: If you have invasive species like Japanese Knotweed or Giant Hogweed, do not attempt DIY removal. These require specialist contractors by law.

Choosing the Right Tradesperson

• Check Qualifications: Look for RHS (Royal Horticultural Society) or Lantra certifications for plant knowledge.
• Insurance: Ensure they hold Public Liability Insurance (minimum £1m) to cover any accidental damage to your property.
• Waste Licence: If they are taking green waste away, they must have a valid Waste Carrier Licence from the Environment Agency.
• Ask about Tools: Do they use petrol, electric, or manual tools? Petrol tools are faster but noisier.

Questions to ask:

• Are you licensed to apply professional-grade herbicides?
• Is green waste removal included in the quote or is it an extra charge?
• Do you have experience with specific plants in my garden (e.g., topiary or delicate roses)?
• Can you provide a fixed quote after seeing photos or visiting the site?

UK Regulations

• Wildlife and Countryside Act 1981: It is an offence to disturb nesting birds. Heavy hedge or shrub trimming should generally be avoided between March and August.
• Waste Carrier Licence: Gardeners must be registered to transport green waste on public roads.
• Tree Preservation Orders (TPOs): Some large shrubs may be classified as trees or fall within a Conservation Area, requiring council permission before significant cutting back.
• Pesticide Regulations: Professional users must hold a certificate of competence to apply herbicides in a commercial capacity.

Common Problems

• Over-pruning: Cutting back too hard into "old wood" on certain shrubs (like Lavender or Conifers) can kill the plant or leave permanent brown patches.
• Improper Disposal: Fly-tipping green waste or burning it in a way that causes a nuisance to neighbours can lead to heavy fines.
• Root Survival: Simply cutting the tops off perennial weeds like dandelions or bindweed will cause them to grow back thicker; they must be dug out or treated systemically.
• Hidden Hazards: Always inform your gardener of hidden cables, irrigation pipes, or delicate ornaments buried near the shrubbery.

Frequently Asked Questions

Is the weedkiller you use safe for my dog/cat?

Most professional gardeners use glyphosate-based products which are generally safe once dry. However, you should keep pets indoors during application and for at least 2-4 hours afterwards. Always ask your gardener for the specific product data sheet if you are concerned.

When is the best time of year to trim my shrubs?

It depends on the species. As a rule of thumb, shrubs that flower in spring should be pruned immediately after flowering. Shrubs that flower in summer or autumn are usually pruned in late winter or early spring. Avoid heavy pruning during the bird nesting season (March to August).

Can you get rid of weeds in my gravel driveway?

Yes, gardeners can use "residual" weedkillers that prevent seeds from germinating in gravel for several months. Alternatively, they can use flame guns or manual scraping for an organic approach.

What do you do with the green waste?

Gardeners can either chip/shred it for your own compost heap, bag it for your council green bin, or remove it entirely to a commercial recycling centre. Removal usually incurs an extra fee to cover tipping charges.

Do I need to be home while the gardener works?

As long as the gardener has clear access to the garden and an outdoor water tap (if needed), you do not usually need to be home. Ensure any side gates are unlocked and pets are kept inside.
